Found my dads original 1971 duster!

Thanks, Noel. Yep, just a pinhole. I just tried heating it up with a soldering iron. Not sure how well it got down into the hole. Here’s a better pic of the hole. If it doesn’t hold, il try cleaning the areas up and adding flux, then a re solder. Can’t hurt

I'd Braze it up with something like this. It flows very fast and should seal well. I worked at a shop that brazed brake fittings and this is what we would use.
